<p>The invention relates to lines of receivers arranged in an area to be explored and provided with geophones (15, 16) in respective receiver positions for measuring seismic waves from the subsoil. The lines of receivers include first parallel lines (10, 20) and second lines (30) parallel to the first lines and located in intermediate positions between the first lines. Seismic waves are emitted from source positions located along the first lines of receivers, and seismic data, representing waves measured by the various geophones in response to the emitted waves, are obtained. Said first seismic data are processed by seismic interferometry in order to estimate other seismic data representing responses, in at least some of the receiver positions, to waves emitted from a virtual source located in a receiver position (35) along a second line (30).</p> |
